Realistically building a production quality database takes 10 years. Building a production quality game engine takes 10 years.
They're building a mobile operating system and the hardware it runs on; that's harder and a moving target.
How long do you think it takes to build a supply chain of hardware that doesn't suck (if it takes 2 years to get moving: you need to start with hardware specs for 2 years from now) and an operating system that doesn't suck when you're also trying to catch up to a major duopoly cranking out devices at an unfathomable volume, with more money than most nation states?
Your standard is "succeed against Google and Apple within 13 years on a shoestring budget with no volume discounts." How can any project clear that bar?
What would you do?
